Oh, thanks for the info about what browser you were using! There was one other user with that black box issue so I wonder what the cause was? I haven't made many games for web browsers so I'll look into this more. As for the player's sanity, we originally had UI to show how much was left, but because of a bug, it doesn't show in our current version. One note I can give is that being in darkness will passively reduce your sanity, so it'll help if you stay in the light for a bit to generate back sanity. You can turn on all candles in the room and fireplaces as well!
